Chinese K40 Laser Safety / What is true?

How safe is a Chinese Laser Cutter? To get answers other than confusing search results from Google, i asked the German Academy for Laser Safety in Berlin how dangerous these cheap chinese laser machines really are. I asked Prof. Dr. Eichler questions you have asked in my comments, so as questions i had never had found a believable or precise answer on the web. Sure not every question could be answered and some are pretty complicated to figure out without having the machine properly tested in a lab, but some answers are pretty interesting specially for beginners! I must confess that there is so much more to talk about when it comes to laser safety, but it would exceed the length of a watchable video. A Special Thanks goes to Dipl.-Ing Mme Schneeweiss and Dr. Prof. Eichler that they took their time to answer my questions! Please as always excuse my crude english but besides scripting, i needed to translate all the answers of Prof. Dr. Eichler in a way they would not falsify their meanings. Disclaimer: I am not responsable for any injury of all kind. This video is informative but does not explain the dangers and hazards of laser radiation in high detail!
